Related Issue

• For the manual, we want to make sure Terraform is well documented with Mycelium (see here: add mycelium support in all of the docs info_grid#617)

Todo

• Add Mycelium to all examples
  • e.g. there is one clear example on how to use Terraform with Mycelium here: https://github.com/threefoldtech/terraform-provider-grid/blob/development/examples/resources/single_vm_mycelium/main.tf
• All examples should include Mycelium
